“Since 1998 we have worked to strengthen our range of products with a presence on the five continents”
“In laboratories we are recognized
for our high quality materials
and high performance”
Since Dorsan’s birth, we have aspired to be the market
leader in liquid filtration solutions for laboratories. Our
pursuit of excellence is the most motivating challenge for the
progress of our company.
We source raw materials of proven quality, from virgin
cellulose fibres and pure cottons linters for our premium
grade analytical filter papers, through to microfiltration
membranes in various materials such as cellulose acetate,
nylon, PTFE or PVDF. Hence, at Dorsan® we manufacture
the most diverse and optimum product lines available on the
market.
At present, we have production centres in Spain, Germany and India. Our vision
is to have branches and commercial offices on all continents. Today, one of our
greatest reasons for pride is to have customers in 57 countries that cover a vast
geographical territory.
In this catalogue you will find the most common references
that are used in international laboratories: Filter paper for
routine use in laboratories, without ash, glass microfibre,
microfiltration membranes, absorbent papers, syringe filters,
etc. Our range is adapted to current needs while our R&D
department is planning new qualitative and differentiated
solutions for the future. Other options for more specific and
concrete applications are offered on request by contacting
our usual contact addresses.
At Dorsan® we are passionate about creating filtration products, we love what we
do and we put all our efforts into it. For this reason, our Company motto, “Living
Filtration”, is not casual or insignificant. We intensely live and feel the processes
of filtration.
FilterPaper
Complete range of ash-free filter paper for carrying out all
kinds of quantitative analysis. Manufactured with high
quality virgin cellulose fibres, then acid treated, and
afterwards washed with demineralised water. Their high
resistance when wet make them ideal for use in filtrations
with Büchner.
Qualitative Paper
Quantitative Paper
Greater filtration speed when using the entire surface of the
filter, recommended for very common processes and
controls, such as the brewing industry for example. High
quality cellulose with different porosities. Retention of 2 μm
up to 50 μm.
Rough surface and smooth surface qualities.
Folded Filter Paper
New concept of filters manufactured with 100% binder-free
microfibre glass. They offer a very appreciable filtration
depth quality, with high flow rates, high load capacity and
particle retention of less than 1 micron. Widely used in
laboratories for various applications.
Fibreglass Paper
Used in cytocentrifuges for the analysis of blood in hospitals
and research laboratories. Absorption of the liquid through the
absorbent paper permits the use of techniques that are faster
than conventional techniques in the examination of cells.
Different measurements in various types of perforations allow
us to offer a variety of products.
Cytocentrifuge Paper
From routine filtration, through to filtration of viscous
liquids such as syrups, oils and essences. Produced
from virgin cellulose fibres and high quality cotton linters.
This type of product is the most recommended for
routine laboratory filtration operations.
Rough surface and smooth surface qualities.

Z-PACK
Dorsan® membrane filters are manufactured with the
latest technology for excellent pore uniformity. A wide
range of levels of absorption for optimal breathability,
drying and absorption.
They are suitable for chromatographic analysis and
for the preparation of samples, as well as methods of
absorption with gel (Southern, Northern and Western
Blot tests). Dorsan® completes its offering with its
popular cellulose nitrate absorption membranes with
excellent protein affinity, high blocking capacity and
compatible with a wide variety of detection methods.

“Cutting edge technology for excellent pore uniformity”
SyringeFilters
“In frequent analysis using syringe filters significantly reduces the filtering time with respect to traditional membrane discs”
We offer two sets of syringe filters.
G Series and T Series.
The G series is characterized by being manufactured
with an outer ring, which gives it greater resistance,
which prevents filter ruptures when working with high
pressures or very dense liquids.
The T-series has a polypropylene prefilter on the
membrane that helps to better prefilter solutions by
extending the volume of the filtration.

Different weights to choose
Dorsan® introduces on the market a wide
variety of absorbent papers for very different
applications. Whether you prefer the economic
reams with a weight of 60 g or the most widely
used of 73 g, in our product range you can find
the one that best fits your requirements and
needs. We offer the possibility of various standard
measurements in sheets or spools. This type of
product is being used at the work tables of
laboratories in different industries: Food and
beverage, chemical-pharmaceutical, cosmetic-
perfume, health services, hospitals, research
laboratories, etc.
We have a special quality called Labcoat that
has polyethylene on one side. This type of product
is very appreciated in industries that need perfect
absorption combined with perfect protection of the
worktable.
The range of Dorsan® extraction cartridges is
very wide. Made from a single piece, they are the
most suitable to be used in Soxhlet laboratory
extractors. They are manufactured from cellulose
fibres, glass fibres and/or quartz fibres depending
on the final application of the product.
In order to choose the correct cartridge, take
into account that it has to pass through the
narrowest part of the upper tip of the extractor. It
should also be 5/10 mm longer than the height of
the Soxhlet extraction chamber. The first digit
represents the inner diameter and the second the
outer length, both in mm.
